Why would anyone want to use aluminum for a mast? Rust resistance?
Lightweight? Flexibility? None of these are necessary characteristics of a
mast. The toughest aluminum alloy made doesn't come close to most steel
alloys. I recall back in the 70's a certain ham(a WB9) decided to use
aluminum to stack some beams. To stiffen it up, he drove a hardwood dowel
into the mast. 6 months later the top half broke off in a wind storm and
came right thru his kitchen roof. True story.
